업데이트 대안을 사용하여 Temurin JDK를 올바르게 설치하는 방법

Temurin JDK 8과 11을 모두 설치하고 싶었는데 다음 단계에 따라 설치했습니다.

wget https://github.com/adoptium/temurin8-binaries/releases/download/jdk8u312-b07/OpenJDK8U-jdk_x64_linux_hotspot_8u312b07.tar.gz
tar xzf OpenJDK8U-jdk_x64_linux_hotspot_8u312b07.tar.gz

sudo mv jdk8u312-b07/  /usr/lib/jvm/temurinjdk-8-hotspot-amd64

sudo update-alternatives --install "/usr/bin/java" "java" "/usr/lib/jvm/temurinjdk-8-hotspot-amd64/bin/java" 1081
sudo update-alternatives --install "/usr/bin/javac" "javac" "/usr/lib/jvm/temurinjdk-8-hotspot-amd64/bin/javac" 1081

하지만 이것이 100% 맞는지 확실하지 않으며 .jinfo 파일을 생성하려면 어떻게 해야 합니까?

답변1

당신은 사용할 수 있습니다Adoptium Debian / Ubuntu 저장소

  1. Eclipse Adoptium GPG 키 추가

    wget -O - https://packages.adoptium.net/artifactory/api/gpg/key/public | sudo apt-key add -

  2. Eclipse Adoptium apt 저장소 추가

    echo "deb https://packages.adoptium.net/artifactory/deb $(awk -F= '/^VERSION_CODENAME/{print$2}' /etc/os-release) main" | sudo tee /etc/apt/sources.list.d/adoptium.list

  3. 필요한 Temurin 버전을 설치하십시오.

    sudo apt update # update if you haven't already
sudo apt install temurin-8-jdk
sudo apt install temurin-17-jdk

  4. 기본 버전 구성

    sudo update-alternatives --config java

원래 AdoptOpenJDK deb 패키지에서 스크립트를 추출하고 다음과 같이 수정된 버전을 사용했습니다.

wget https://github.com/adoptium/temurin17-binaries/releases/download/jdk-17.0.1%2B12/OpenJDK17U-jdk_x64_linux_hotspot_17.0.1_12.tar.gz

mkdir -p /usr/lib/jvm

sudo tar -xvvf OpenJDK17U-jdk_x64_linux_hotspot_17.0.1_12.tar.gz -C /usr/lib/jvm/

sudo ./java-alternative install /usr/lib/jvm/jdk-17.0.1+12
sudo ./java-alternative set /usr/lib/jvm/jdk-17.0.1+12
…
sudo ./java-alternative remove /usr/lib/jvm/jdk-17.0.1+12
